McLaren CEO Zak Brown has taken another swipe at Red Bull F1 team boss Christian Horner for “making excuses” and “not taking owne🐻rship” over a number of ꦗissues.

Since McLaren’s resurgence on-track, Brown hasn’t been afraid♓ to lock horns with Horner.

Brown was vocal in his 🌊criticism of Red Bull when they exceeded F1’s co꧟st cap.

He cl⭕aimed Red Bull’s overspending ‘constituted cheating’ which di𒁃dn’t go down well.

More recently, Brown was outspoken♈ amid Horner’s inappropriate behaviou💃r scandal calling for “transparency”.

Similarly, the American poked fun at Red Bull when they lost Adrian Newey, stating the team will likely lose more key personnel with “CVs 🌳floating around”.

In an interview with the , Brown shed light on his relationshiꦿp with Horner and why it⛎ has deteriorated.

"I've known Christian for about 25, 30 years. We used to rac🌳e against each other. I would say we used t🌄o get on,” he said.

"I believe in transparency. I believe in putting your hand up when you get something wrong. The cost cap, the excuses behind that, I never really heard a 'we j🦂ust got it wrong'. I heard excuses and not 🍃taking ownership.

"When someone breaches the cost cap, and doesn't seem to kind ofꦺ take it seriously, that's kind of hitting the integrit𓆉y and core of the sport.

"To me, it's not perso♏nal. It's protecting our sport.”

Brown again made reference to Horner’s pre-season controversy,🀅 a🙈dding it wasn’t “consistent with our values”.

"And when I see things not consistent with our values, I'm going to speak up about it because it's important people understand where we're comingꦐ from,” he added.

"I realise that's not necessarily always going to be popular, or make friends with🧜 everyone in the pit lane, but as long as I'm friends with McLaren, our fans, our partne🔯rs, that's what's most important to me."
